ELECTRlC FIRE AND BURGLAR ALARM.

SPECIFICATION forming part of Letters Patent No. 359.823, dated March 22, R 8'7.

Application lilcll June 24,1856.

To (LZZ whom it may concern:

Be it known that l, SIGFRIED Tliussro, attorney at law, a subjectof theEmperor of Austria, residi ng at-Prague,in theProvince olBoliemia, in the Empire of AustriaHungary, have invented certain new and useful Improvements in Electric Fire and Burglar Alarms, (for which Letters Patent have been obtained in France, No. 176,177, dated May 15, 1886; in Belgium, No. 73,128, dated May 15, 1886; in Italy, XX, 19, 936, and XXXLX, 296, dated June 30, 1886; in Luxemburg, No. 723, dated August 15, 1886, and in Spain, No. 6,206, dated November 2, 1886;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the some, reference being had to the ac companying drawings, and to letters or fig urcs of reference marked thereon, which form a part of this specification.

Referring to the drawings, Figure 1 is a diagram of my improved system of fire and burglar alarm. Fig. 2 is an elevation of the circuit-breaker or electric-impulse transmittor for the local stations and the parts connected therewith and controlling the same.

This invention relates to that class of de vices known as fire or burglar alarms which are operated and controlled. by electric currents.

The object of my invention is to provide improved means whereby an alarm, either audible or visible, or a permanent or recorded alarm, may be given at a central station distaut therefrom in case of a fire breaking out, or in case of an. attempted burglary at such distant station.

To these ends the invention consists in an alarm system comprising a main or central station, an indicator at said station, a main electric circuit, any number of secondary stations, a local circuit, and a transmitting-instrument for each secondary station, the latter operating to transmit electric impulses differing in nature from those transmitted by the instruments of the other local stations to said central or main station, substantially as hereinafter fully described.

The invention further consists in the com Serial K0. 206,097. (No-model.) Patented in France May 15, 1856, X0. 176,177; in'lielgium in liuxcmburg August 15, l8-6. No. 723, and in Spain bination, with each local circuit, of the system of a shunt'circuit and a signaling device in said circuit, substantially as hereinafter fully described.

Lastly, the invention consists in some ofthe details of construction of the instruments or apparatus used, substantially as hereinafter fully described.

in the drawings, A indicates the main circuit, that extends from a main or central station, I, to any desired number of local sta' tions, 1 2 3, 850., connected with the main line by branch lines or wires [1. Each of the local stations, which "may be a public building, bank, warehouse, or other building, has a local circuit, H, in which are included all the points, 71., to be protected-such as shutters, doors, windows, safes, In order to close the local circuit when any one of the points it is unauthoritatively tampered with without necessarily closing it at all points It, these are connected in multiple arc in any desired or well-known manner. in the main and each local circuit is interposed a transmitter,which consists, essentially, of a circuit breaker operated from a suitable train of cloclcgeariug, C.

The circuit-breaker, its operating mechanism, and parts operating in conjunctionthercwith are mounted on a suitable frame, and said circuit-breaker consists of a metallic wheel, B, that has upon its periphery a predetermined number of insulated points or strips, bx, arranged in a predetermined manner and of a predetermined extent, so that the contacts of all the wheels of the transmitters will differ from one another and a different signal will be transmitted from each local station to the main or central station, the linecurrent passing from the central-station battery Y through the transmitter of each station, through its frame, and thence by wire If to earth, as at G.

Then the transmittcrisat rest, and whether the system is used with a normally-interrupted or anormally-closed circuit, one of the strips or points he will lie in contact with a spring, b, that is connected with the branch wire I) of the main line A.

D is a lever fulcrumed at (I, one end, (1", of [00 which lever is hooked and engages a notch in an annular projection of the wheel B, the other end, (1 of said lever lying in the path of the outer end, 6 of an armature-lever, E, fulcrumed at e. the said parts forming an escapement; and E is an electro-magnet included in the local circuit H. The wheel 13 is connected with the transmitting-wheel c of the train of clock mechanism 0 by means of a toothed wheel, b".

The lever D is held in engagement with the notch in the wheel B bya spring, (1, while the armature-lever E is held out of contact with the electro-magnet by a spring, 6; and}; is a stop pin that limits the movement or the armature in one direction, or away fronrthe electro-magnet. 1

It will be seen that when the electro-magnet E attracts the armature-lever E the outer end, 6 of the latter will engage the free end of lever D and disengage its hooked end (2 from the notch of the transmitter-wheel B, which, under the action of the train of clock mechanism C,will make one revolution,during which the contact points or strips on the periphery of the wheel will successively pass under the contact-spring B andsuccessively interrupt the main circuit, and transmit to the indicating or recording instrument 1 at the main station aseries of electric impulses, fromthe nature of which the location of the local station from which the signals are trans mitted is made known, the line-current. as above stated, passing from the battery Y at the central station through the recording-in.- strument and line-wire to spring I), the wheel B, and wire b" to earth. The arm D of lever D is formed in two sections, the outer section, d being articulated to the inner section, so as to swing upward. This is necessary to allow the armature-lever E to return into its normal position after having been attracted by the electro-magnet and actuated the lever D, as described.

The local circuit is normally interrupted by the connections with the points to bepro-l tected or guarded, these connections being so arranged that when tampered with the local circuit will be closed and the operations above described result therefrom.

In order that an attempt at burglary or the breaking out of a fire may be made known on;

the premises themselvesto'a watchman, for instanceI interpose a signaling-instrument,

K, in a derived or secondary circuit, H, such signaling-instrument being of any desired or preferred construction to giveeither'a visible or an audiblesignal, or both.

circuit is normally interrupted and is closed simultaneously with the closure of the local circuit by the armature-lever E, which has an arm, 6 to which is secured a contact-spring,

0 that makes contact with a screw, 6, the

current passing from local battery Xtolsignaling devices K,lthence to lever-spring e contact-screw 6, back to battery, whiletthe localcircuit currents pass from battery X to points h h h, &c., to ele'ctro-magnet and back to battery, as shown in Fig.1.

I have deemed it unnecessary to illustrate in detail the recording or indicating instrument at the central station, or the connection of the local-circuit with the various points of a local station to be protected in case of firle or an attempt at burglary, for the reason that the construction of such instrument andthe This secondary connections are well known, and the latter;

vary according to the nature of the part to which they are applied, and for the further reason that they do not form a part of my inveution.

Having now described my said invention and how the same is to be performed, what I claim, and desire to secure by Letters Patent, is-

The combination of the electromagnet E, the circuit-breaker B, provided with an an nnlar project-ion having a notchin its periphcry, with thelever D, having the articulated I SIGFRIED TAUSSIG.
